Northern Rocky Mountain Science Center

Home

Our Northern Rocky Mountain Science Center's priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community.  Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact Claudia Regan at cregan@usgs.gov or Judy O'Dwyer at jodwyer@usgs.gov.

Picture This: A National Climate Change Viewer that Helps Land Managers and Decision Makers Plan for Climate Change

The enormity of the challenge posed by climate change makes it difficult to visualize and understand on the ground. Even though wide-ranging impacts are visible today, it’s hard to envision how tomorrow’s changes will take shape. What will the temperature be in Portland in the spring, or how much rain might Dallas get in the fall? The USGS has a tool that can help address that challenge.

Evaluating corticosterone as a biomarker for amphibians exposed to increased salinity and ambient corticosterone

Physiological biomarkers are commonly used to assess the health of taxa exposed to natural and anthropogenic stressors. Glucocorticoid (GC) hormones are often used as indicators of physiological stress in wildlife because they affect growth, reproduction and survival. Increased salinity from human activities negatively influences amphibians and...

Metal accumulation varies with life history, size, and development of larval amphibians

Amphibian larvae are commonly used as indicators of aquatic ecosystem health because they are susceptible to contaminants. However, there is limited information on how species characteristics and trophic position influence contaminant loads in larval amphibians. Importantly, there remains a need to understand whether grazers (frogs and...
